I used this to mark quilting lines on a table runner:
I used a blue one and the lines are still there! I've put it in the washer on rinse - still there. Soaked in the sink with OxyClean - still there. Now what?
It's in the thread on the quilt line, but also on the fabric where I sewed away from the line I'd marked.
This is my mother's Christmas present! Help! Help! Help!
